Still another object of the invention is tozprovide a method or packaging angel food cakesinmerchandisable packages wherein the steps. of

cooling, dumping and wrapping the individual cakes may be dispensed .with, thereby reducing the packaging costs, which saving may be passed on to the ultimate consumer.

Still a further object of bakery products, which is adaptedtobe' stacked for delivery or display purposes without damage to theproduct housed therein. j z a a These and other objects areattained by the means described herein and disclosed in-the accompanying drawing, inwhich, the singleffl'gure is a vertical section taken through, a merchandisable package embodying the 'presentf'invenetlon.,'- v

Heretofore, cakesof thean'gel icod variety were baked in suitable utensils, after which 'theywere cooled, dumped out upon suitable trays, andft'hen individually wrapped or packaged] for the'ultimate consumer. By reason of such treatment, the air cells ofthe cake were often ruptured, thereby reducing the size or volume of the cake and increasing-its density with the result that the product delivered to the ultimate consumerwas tough and unpalatable.

The present invention'isdirected, among other things, to the provision of a merchandisable package for angel food cakes,'which will permit them to be delivered to the ultimate consumer having substantially the same volume and degree of tenderness as they had when removed from the baking oven.

With reference to the figure, the numeral I0 indicates a bake pan or other utensil of-the gen- I, the I invention v I provide a merchandisable package tor-angel iood whichft'he cake better I cake, .denoted generally by the numeral 2 l ,will

'It should be understood,

that angel cakes 'arefmade from a batter'th'e bulk "of whichpom- [prises egg; whites thoroughly aerated by whipping, whereby the batter,- compfrises' literallyrn'il- "lio'risjoffminute air cells. During "thejbaking process these, air cells expand causing the cake to rise thereby imparting to the cake a light, fluify ftekture. AsIthe cake rises incident tapering-i it I clingsto theside .walls of the pan lnfsuch a'manner fits to support the central, portionfltherefof, and to provide an'effective air seal between abut- "ting faces of the cake and pan walls. Thefexposed top-edge of thecake acquires a pliable' but dense crust l6, during the baking operation. This crust, it 'should be noted extends betweenl the inner'and outer walls of the pan, land 'compr,i ses an efiective air seal over the cake top.

It should be noted that so long as'thj'efindifvidual air cells of the cake remain intact; and

unruptured, the volume" or size of thecakeiwill "be-a maximum and its texture willbe lightQflufiy and tender;

-In.order that the baked angel foodlcake productfmay be' delivere'd'to the ultimate consumer is packaged'forsalein thesame pan in which it having substantially the samephysical characteristics as when removedfro'mjthej baking oven, it

was baked. Such packaging comprises the single step of applying a cover-member l1 over the upper open or top portion of the pan.

Cover member I! is preferably a semi-moisture proof membranous sheet of material, which will permit some of the cake moisture to be dissipated therethrough. As illustrated, the cover member preferably makes physical contact with and alongthe upper edges of both the inner and outer pan walls as at 22 and 23, respectively, whereby to completely close the upper open end of the U-shaped pocket in which the cake is disposed. The lower edges IQ :of the cover member s f ll may besnugly secured to the outer wall I2 by means of a retaining member l8'which circumscribes it as shown. Retaining member is may comprise an elastic band, a length of cord or wire, or a length of tape, or the like.

When so pack-aged, angel food cakes, after havr n been transportedby truck several hundred miles and stored for over a; week are, when unpackaged, as large, tender and palatable as when baked.

The" cost of packaging angel food; cakes by the 'hereinabove described method is considerably less than the cost ofpackaging similar cakes in inutensils in which they are baked and wherein thecakes 'will remain large, light, tender and fluffy eve nthough stored for a week or more.

It should be'un'derstood that various modifications and changes in the structural details of the device "may be made, within the scope of the appendedclaims, without departing from the spirit of the invention.

What is claimed is:

1. An angel food cake package which com- :prises an open topped; tubed aluminum cake pan dividualdisposable containers or cartons,as done in the past. Heretofore it was necessary to per;-

rnit the cake to 0001 after baking, after which the cake wasturned out of the bake pan onto-q, 1

Ta tray, or 'the like. Each cake was individually wrapped and then boxed in a disposable con tainer for delivery to the purchasen-"Suc'h paok- I.

aging procedure was expensive from the standpoint of laborrequired and materials used. In

addition thereto, the cake itself was adversely -,a'fiected by 'the handling incident to 'thetpack'a'gsmaller than'the' size of the cake when it came containing an angel food cake baked therein, said cake characterized by a myriad of easily "rupturable air cells, a semi-moisture proof cover member disposed across the open top of said pan ror completely housing said cake, and means for 'securing said cover member to said pan and across said opentop, wherebytr'ansportation and merenandismgcr the cake is facilitated and the cake a remains in a normal condition retaining for a bilit'y,-'which method con'iprises the--steps0f bakfromthfe oven. The texture of the cakewas likewise-afiected adversely by such'handlin'g. These i disadvantages' are completely obviated by the herein disclosed merchandisable package.

Inasmuch as cakes of the angel foo'd variety ihaveatend'ency to corrode or eat away certainmetals with which they are brought into pr'oor from copper however, I have found that from the standpoint of durability, initial cost and upkeep, aluminum pans are the most satisfactory. should be observed that thepans are adapted j to eused' over and over, being exchanged'when I i "'emp'tyjfor another pan containing a cake, in a mfanner' similarjt'o the exchange of empty milk bottles for filled ones. It should likewise be ob- 1 s 'erved that-such packages may be stacked, for the purpose 'of' transportation or'displa'y. Without "damage to the "contents thereof. Each heattube "2'0 comprisesan' upstanding hearing or support member upon which plane articles .suchas trays and the lik'e may be disposed, which in turnmay contain cake pans or other articles of merchandise. This'ls in-sharp contrast to the vprecautions required to prevent crushing of angel food cakes when individually packaged in disposable card delivered 'to the ultimate consumer in the same is apparent that I have ing an angel fo'od cake batter. in' a tubed cake I food cake, of then'pl'acinga-semiqnoisture proof displacement cover-member over the upper; exposed portion of the cake and over the upper perimeters of the cakepa'n, and of then securin'g'sa'idco'ver member in place" against accidental or unintentional angel-food cake package which comprises in combination, an aluminum bake pan including a bottom and 'a pair of inner andouter concentric upstanding walls which form an annular U- 'sha'pe'd c'ake receiving pocket open at its'upper end, an "angel food cake baked insaid i j pocket; 8; semi-moisture "proofjcover memberdisposed across-- said' pocket-and contacting the perimeter of each of said ".upstanding'walls for completely enclosing" the-bake housed withinsaid pocket, andmeans'circumscribing' said outer wall across said-l pocket. 1
